CURBING-PLATE FASTENER.

SPECIFICATION forming part of Letters Patent No. 738,334, dated September-8, 1903.

Application filed November 3, 1902. Serial No. 130,001. (No model.)

To @ZZ whom, it may concern:

Beit known that I, ISRAEL L. LAND1s,a citi- Zen of the United States, residing at Chicago, Cook county, Illinois, have invented certain new and useful Improvements in Curbing- Plate Fasteners, of which the following is a specification.

This invention relates to devices for tying or securing lne-tal plates or protectors to structures such as natural and artificial stone and brick and the like, and has in view particularly the protection of the outer edges of stone and brick walks exposed to the wear and tear of trafiic liable to shear ott, chip, and break same, making them unsightly in appear-ance and materially reducing the life ot .such walks.

The objects of the invention are to provide inexpensive and practical ties applicable with unskilled labor and with simple tools which shall not weaken the structure, which shall obviate protruding nail, screw, or bolt heads and leave the walk or other structure perfectly even and smooth on its wearingsurface, which shall eftectually protect the tie itself against the action of the elements, and the principles of which shall be adaptable to a large variety of modifications suited to varying conditions or structural means.

The invention consists in the various details of construction and combinations of parts, all as hereinafter described, and particularly pointed out in the claims, and will be more readily understood by reference to the accompanyingr drawings, forming a part of this specication, and in which- Figure lis a section of awalk made of stone or coarse earth having a iiat metal plate secured to the outer edge thereof by means of my invention. Figs. 2, 3, 4:, and 5 are enlarged detail views of several modications of the tie bolt or rod and its holding means proper.

In the drawings, 2 represents the walk; 3, the metal plate securedth'ereto; 4, the bolt or rod; 5, the transverse holding rod or wedge, and 6 and 7 the apertures provided for same in the walk 2. 8, 9, and l0 in the detail views represent various forms ofeyes or apertures Suitable apertures 6 and 7 having been made in the walk 2 through, respectively, its perpendicular and horizontal surfaces, the bolt t is inserted through the hole or aperture 6 and the wedge or cross-bolt 5 inserted through either of the openings 8, 9, and 10. Molten metal is poured in through the aperture 7, which will quickly iiow throughout the apertures 6 and 7, filling up the unoccupied space and incasing the boitliand cross-bolt or wedge 5 even with the top of the aperture 7. The tie is thus not only securely embedded in the walk, but is well protected against rust, corrosion, and the disintergrating influence of the elements, a fusible metal such as lead being preferably employed to lill up the apertures.

When a Wedge is employed, it is obvious that the aperture 10 may be made of such length and the aperture 7 placed in such position with relation to said aperture l0 as to draw the bolt inward, and thus clamp the plate 3 very securely against the walk 2. It is also obvious that a rod long enough to constitute a lever having its fulcrurn either at the top or bottom portions of the aperture 7 may be inserted through the holes, eyes, or

vapertures 8, 9, and 10 and the bolt 2i pried inwardtherewith while the molten metal is poured in, then cutting said lever -rod off flush with the top of the walk, or a flexible rod 4 may be used with suitable lever-engag,Jrg ing means upon its inner end for the same purpose. Again,molten` metal may be poured in upon and around the several forms of bolts or rods shown, and the solidified metal, filling the apertures 8, 9, and 10, takes the place of the cross-bolt or wedge, and the rod t may be formed with a hook or spur for that purpose in lieu of the eyes or apertures 8, 9, and 10, all ot' which is so clearly buta slight modification of` the invention as to be fully covered by the modifications illustrated as to make additional drawings superliuous. While the illustration in Fig. l shows a plain plate 3, it is obvious that other forms may just as well be employed in connection with the tie illustrated.

As other minor changes may be made in the details of my invention by one skilled in the art Without departing from the spirit thereof, I do not confine my invention to the specific constructions herein shown and described.

IOO

Having thus described my invention, I claim as new and desire t0 secure by Letters Patentl. In a platefastener, the combination, with the structure and the plate, the former having a mold-aperture and an ingate leading thereto, of separate interlocking members or core-pieces and the cast thereupon integrating same.

2. In a plate-fastener, the combination, with the structure and the plate, the former having a mold and an ingate leading thereinto, of separate interlocking members engaging said plate and projecting into said mold, and the cast thereupon substantially integrating same.

3. In a plate-fastener, vthe combination, with the structure and the plate, the former having a mold-cavity-formed in one side of the structure and an ingate leading tbereinto formed in another side of the structure, of separate members interlocking each other and one thereof engaging said plate, and the cast in said mold and upon said members, together constituting the fastener.

4. In a plate-fastener, the combination, with the structure and the plate, the former having intersecting holes, the plate-engaging member adapted for one of said holes and the cast thereupon filling both of said holes and thereby interlocking said plate and structure.

5. In a plate fastener, the combination, with the structure and the plate, the former having intercommunicating holes formed in planes substantially at right angles to each other, a plate-engaging member in one of saidv holes and the cast formed upon said member in the other of said holes.

6. -In a'plate fastener, the combination, with the structure kand the plate, the former havingholes made in intersecting planes, and

thelatter having a rod or bolt adapted to be contained in one of said holes, the cast, forming said rod or bolt fastener, occupying the other hole and holding said plate and rod or.

with the structure and the plate, the former having intersecting holes projecting from different sides thereof, of the fastener consisting of the plate-engaging member for one of said holes and the cast formed thereupon and substantially integral therewith for the other hole and said cast and member interlocking said plate and structure.

9. In a plate fastener, the combination, with the structure and the plate, the former having intercommunicating holes formed in planes substantially at right angles to each other, of the fastener consisting of a rod or bolt adapted to be contained in one of said holes, a cast thereupon and substantially integral therewith lling both of said holes and forming with the fastener substantially an integral portion of the structure.

In testimony whereof I have hereunto set my hand in the presence of two'witnesses.

ISRAEL L. LANDIS.
